Following up this article..Fukushima worker “Shortage of nuclear worker is becoming serious”
Having finished the radiation survey in reactor1 [Link], actual Fukushima worker Happy11311 tweeted like these below,,
続き1:今日は昨日東電が発表してた1号機の原子炉建屋調査をやったみたいでし。詳細な結果はまだオイラ達には来てないけど、相変わらず線量は高かったみたいでし。去年、南東側の配管スリーブから湯気が上がってた場所は4000msv/h位みたいでし。

Tepco conducted the robot survey of reactor1 as they announced yesterday. We haven’t received the details of data (Tepco had not published the data at this time) yet, but sounds like the radiation level was high as usual. It was 4000mSv/h around where the steam was coming up from the pipe sleeve on the South-East side of the building last year.
*It was not 4000mSv/h, but 5000mSv/h. He misunderstood the number.
<End>
続き2:去年が確か4700msv/hだったから少し下がったけど、まだまだ人間が近づける線量じゃないでし(>_<)今日はロボットが最初動かなかったみたいで作業完了時間が遅れたみたい。いずれにしても原子炉建屋の高線量区域はしばらくはロボット主体の作業になりそうでし。

Maybe it was 4700mSv/h last year, so it slightly decreased (* Because it was actually 5000mSv/h, it slightly increased. He misunderstood the number.) but human can never approach it yet. Today robot didn’t work at the beginning, the ending time was later than they scheduled. Anyway, we must rely on the robots at the highly contaminated places in reactor building for a while.
<End>
続き3:そうは云っても作業員が入らなくちゃならない高線量区域作業も沢山あるんだ。多分100msv/h～120msv/hの場所は人海戦術になる可能性があるでし。ただ作業員が集まるかが問題で今も下請け企業は作業員集めるのにすごく苦労してるでし。

Anyway, there are still a lot of highly radioactive places where human workers have to go. Probably we must take the “human-wave tactics” where is about 100 ~ 120 mSv/h. but the problem is if we can collect enough human workers, even now sub-contract companies are struggling to collect nuclear workers.
